Final answer:
A monsoon is a density dependent limiting factor, while the other options are density independent limiting factors.
Step-by-step explanation:
The correct answer is 4. a monsoon. A density independent limiting factor is a factor that affects a population regardless of its size or density. Factors such as lots of rain, decrease in temperature, and increase in predators can all have an impact on population size and density. However, a monsoon is a density dependent limiting factor, as it specifically affects populations that are densely packed together, such as in certain regions of Asia.
